Master advanced Oracle Linux 8 administration with a focus on software management, high availability, patching, and automation tools. This course prepares learners to streamline operations and enhance system reliability. Delve into the critical aspects of Oracle Linux 8 administration, including efficient software management with DNF, implementing redundancy and high availability, and leveraging automation tools such as Terraform, Ansible, and Packer. Learners will also discover strategies for live patching and maintaining system uptime. By completing this course, participants will be equipped to optimize Oracle Linux environments for performance, resilience, and scalability. This course uses practical examples and actionable insights to guide learners through advanced administrative tasks, emphasizing real-world problem-solving and efficient system management. Learners will develop the expertise needed to automate and secure their Oracle Linux infrastructure. This course is part two of a three-course Specialization designed to build a complete and cohesive understanding of the subject. While it offers valuable skills on its own, you'll gain the most benefit by progressing through all three courses as a structured learning journey. This course is based on Oracle Linux Cookbook, by Erik Benner, Erik B. Thomsen and Jonathan Spindel.

Syllabus

Software Management with DNF
- This module provides an in-depth exploration of DNF (Dandified YUM) for effective software management on Linux systems. Learners will discover how to configure repository settings, automate updates, and create custom RPM packages for efficient deployment. It also covers strategies for maintaining systems in secure environments without internet access.
Eliminating All the SPOFs! An Exercise in Redundancy
- This module covers the design and implementation of high-availability (HA) systems to eliminate single points of failure (SPOFs). Learners will explore tools like HAProxy, Corosync, Pacemaker, and GlusterFS to build resilient architectures. The course focuses on real-world strategies for redundancy, load balancing, and cluster management.
Oracle Linux 8 – Patching Doesn't Have to Mean Rebooting
- This module covers the use of Ksplice for patching Oracle Linux 8 systems without requiring a reboot. Learners will gain hands-on knowledge of configuring Ksplice for both internet and offline environments, as well as understanding its role in enhancing system security and availability.
DevOps Automation Tools – Terraform, Ansible, Packer, and More
- This module explores essential DevOps automation tools such as Terraform, Ansible, and Packer, focusing on how they can be used to streamline infrastructure provisioning, system management, and secure configuration. Learners will gain practical skills in implementing and managing automated workflows, improving deployment efficiency, and creating portable, repeatable environments.
